Abstract

The utility model discloses a medical needle safety device, including shell body and interior casing, interior casing with shell body off -centre is cup jointed, the shell body can be relative interior casing rotates, interior casing head end is equipped with the first opening that supplies medical needle needle tubing to pass through, the inner shell can needle needle tubing axial displacement medical relatively, interior casing is terminal to be reached the shell body end is equipped with second opening and the third opening that supplies medical needle syringe needle to pass through respectively, the second opening is located the terminal center of interior casing, the third opening is located the shell body is the position at center relatively. The utility model discloses a protector can bend the needle point to this destroys syringe needle, because the protection needle point of casing tail end and clip can not expose outside yet, has avoided leading to the fact the injury to the people simultaneously.

Description

A kind of safety shield for medical needles

Technical field

This utility model relates to a kind of safety shield for medical needles, belongs to technical field of medical instruments.

Background technology

Medical needle, as hypodermic needle, biopsy needle, intravenous introducer, trocar, seal wire, thoracentesis needle etc., these become dangerous goods can be stained with medicine or patient's pathogen with it after use after, and due to unexpected too numerous to enumerate by these cases of stinging with the apparatus of syringe needle, in order to avoid stab by this type of contaminated thorn part or therefore and infect health risk, more existing preventers in prior art, but more existing preventer protection not in place, often also likely suffer secondary injury.

Moreover, existing multiple medical needle is disposable, use the rear pin that simply puts to emit and just abandon immediately, because pin emits and insecure, also can damage the staff of these medical wastes of process, even some lawless person reclaims these medical needles abandoned again, potential safety hazard is larger, prior art does not also find the preventer more thoroughly for this situation, is about to the syringe needle after using and thoroughly damages, can not only avoid stabbing the recycling that yet can prevent person who is ambitious or tenacious of purpose.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of safety shield for medical needles.

For solving the problem, the technical solution adopted in the utility model is:

A kind of safety shield for medical needles, comprise shell body and inner housing, described inner housing and described shell body bias are socketed, described shell body can rotate relative to described inner housing, described inner housing head end is provided with the first opening passed through for medical needle needle tubing, described inner shell can move axially by medical needle needle tubing relatively, described inner housing end and described shell body end are respectively equipped with the second opening and the 3rd opening that pass through for medical needle syringe needle, described second opening is positioned at described inner housing distal center position, and described 3rd opening is positioned at the position that described shell body is partial to center.

Preferably, described shell body inner surface is provided with female thread, and described inner housing outer surface is provided with the female thread adapted with described external screw thread.

Preferably, be provided with loading layers inside described shell body end, in described loading layers, have implant.

Preferably, described shell body and described inner housing are cylindrical shape housing.

Preferably, described loading layers inner stuffing is viscous silica gel.

Preferably, the circular open that described second opening is equal with sized by described 3rd opening.

The beneficial effect that this utility model reaches:

Preventer of the present utility model can be enclosed within medical needle head before medical needle uses or after using, and preferably puts before use, safer.After putting, syringe needle can stretch out through the second outlet, the 3rd outlet successively, to be used complete after, first regulate the distance of inner shell and medical needle head as required, and then regulate shell with the relative position of inner shell, needle point to be contacted as far as possible with casing ends, then outside rotational shell (namely to the direction increasing shell and inner shell overall length), needle point is made to avoid the 3rd other parts of opening and casing ends relative, last inwardly rotational shell (namely to the direction of reducing shell and inner shell overall length), and turning over bending of needlepoint by pressure in journey;

Needle point can also be blocked by the implant in shell body end loading layers, so both prevents leaking of residue in needle tubing, also thoroughly damages needle point, avoid stabbing people and being recovered.Even if pole in particular cases this preventer comes off from medical needle, needle point also can not work the mischief.

Accompanying drawing explanation

Fig. 1 be in embodiment medical needle and preventer assemble after structural scheme of mechanism;

Fig. 2 is the structural representation of preventer in Fig. 1;

Fig. 3 is that the structure of Fig. 1 housing end is with intention.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.

As Figure 1-3, a kind of safety shield for medical needles, comprise shell body 2 and inner housing 1, inner housing 1 is socketed with shell body 2 bias, shell body 2 can rotate relative to inner housing 1, inner housing 1 head end is provided with the first opening 3 passed through for medical needle needle tubing, inner shell can move axially by medical needle needle tubing relatively, inner housing 1 end and shell body 2 end are respectively equipped with the second opening 4 and the 3rd opening 5 that pass through for medical needle syringe needle, second opening 4 is positioned at inner housing 1 distal center position, and the 3rd opening 5 is positioned at the position that shell body 2 is partial to center.

Particularly, shell body 2 inner surface is provided with female thread, and inner housing 1 outer surface is provided with the female thread adapted with described external screw thread.

Shell body 2 can be suitable for the syringe needle of different length with this design of inner housing 1, simple and convenient.

Further, loading layers is provided with inside shell body 2 end, implant is had in loading layers, this loading layers inner stuffing is viscous silica gel, alleged viscous silica gel is the sticking silica gel of band herein, and needle point can also be blocked by the implant in shell body 2 end loading layers, so both prevents leaking of residue in needle tubing, also thoroughly damage needle point, avoid stabbing people and being recovered.Even if pole in particular cases this preventer comes off from medical needle, needle point also can not work the mischief.

Further, shell body 2 and inner housing 1 are cylindrical shape housing, the circular open that the second opening 4 is equal with sized by the 3rd opening 5.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
